awk/sed/bash to process multiline output

[shacker]

Trying to process this output:

--------------snip---------------------
Change 123 by john

foo=bar
x=y
t=111

Change 456 by jim

foo=bar2
x=6

Change 789 by larry

foo=baz
hoo=hoo
t=222
--------------snip---------------------

Into something like this:

123 john 111
456 jim
789 larry 222



Any thoughts? awk, sed or bash will do.

awk '/^Change/ {
          printf r || f ? ($2 " " $4 " ") : ("\n" $2 " " $4 " ")
          f = 0
          r = 0
    }
/^t=/ { 
          print $2
          f = 1
    }
END {
          if (! f) 
        print ""
}' FS="[= ]" r=1 filename
